Problems solved by technology

The dispersion of the optical characteristics and that of the signal characteristics in both image detecting systems can be adjusted to some extent on the image detecting unit side and on the image processing unit side respectively, however the adjustment is still inadequate.
Hence, it is impossible to combine the image detecting unit and the image processing unit each of which is manufactured independently and this inhibits an improvement in productivity.

Embodiment Construction

An embodiment of the present invention will now be described in detail with reference to the accompanying drawing.

FIG. 1 shows the schematic construction of a stereoscopic image processing apparatus, which comprise a stereoscopic image detecting unit 10 including two CCD (Charge Coupled Device) cameras 11, 15 and a stereoscopic image processing unit 50. This stereoscopic image processing apparatus is mounted on a vehicle so as to obtain distance information from the vehicle to an object by processing a pair of picture images taken by two CCD cameras 11, 15 and to recognize the configuration of roads or solid objects based on distance information obtained.

The two CCD cameras 11, 15 are mounted in the vehicle in a horizontally aligned relation at a prescribed distance away from each other. These two cameras have a variable shutter speed mechanism and are operated synchronously with each other. The optical axes of lenses 12, 16 are arranged in parallel with each other. One CCD camera 1...

Abstract

A stereoscopic image detecting unit has a first non-volatile memory for storing inherent camera characteristic data therein and an image processing unit has a second non-volatile memory for storing inherent circuit characteristic data therein. When the stereoscopic image detecting unit is connected with the image processing unit through a serial cable and video cables and then electric power is turned on, the inherent camera characteristic data are sent to the image processing unit. In the image processing unit, based on the camera data sent from the image detecting unit and the circuit characteristic data in the image processing unit, data for correcting the optical dispersion between two cameras and that of signal characteristic are established.

Description

1. Field of the InventionThe present invention relates to a stereoscopic image processing apparatus for a vehicular distance detecting system and more particularly to a stereoscopic image processing apparatus capable of arbitrarily combining for use an image detecting unit and an image processing unit.2. Prior ArtsModern advanced safety vehicles are equipped with a distance detecting means for detecting a distance between the self vehicle and other vehicles, obstacles and surrounding objects. Such a distance detecting means comprises an image detecting unit for taking picture images of solid objects, lane markers and the like and for outputting image signals and an image processing unit for processing those image signals into distance information.A typical example of the image detecting unit employs optical systems, i.e., a pair of left and right hands cameras disposed in a horizontally aligned relation at a prescribed distance apart from each other.The image processing unit success...
